Paid an LLC insurance premium with my personal card. 6,800 to unwind.

The detail that gets me is the timing. Four day freeze, 48 hour cancellation window. There was no version of that week where you had a comfortable option. Do you know if a lapse and rebind would actually have cost much? I'd guess a few hundred in higher premium and a gap in coverage, which is real risk on an occupied duplex but survivable.

On the management side this comes up more than people think. I have owners with IRA-held property and my standing rule is that every expense on those files goes through me, billed to the entity, and I never take a personal card from the owner even when they offer. I've had owners get annoyed about a 60 dollar lock rekey sitting three days waiting on funds. Annoyed is cheap.

Worth adding that hazard binding rules and how fast a cancellation takes effect vary by state, so the 48 hours solder had isn't universal. Check the notice requirements where the property sits before you assume you have a week.

6,800 for an opinion sounds high until you price the alternative. I've watched a colleague get a five figure bill just to reconstruct records after the fact, and that was before anyone had an opinion to rely on. Paying for the opinion while your paper trail is eleven days old is the cheap version of this.

The second bank account idea is good and I'd go further. The freeze happened because you sent a wire from an account that rarely sends wires. Fraud models flag exactly that. If your LLC account moves money twice a year, tell the bank in advance every single time, with the amount and the counterparty, and get a reference number. I do it now and my freezes went to zero.

Also the 90 day reserve number. What's 90 days on your duplex? Taxes, insurance, and whatever a bad HVAC month looks like. For a small duplex I'd want more like 6k sitting idle in the LLC than three months of average expenses, because the thing you're insuring against is the abnormal month, not the average one. That's real drag on your yield and you should price it as such when you decide whether an IRA should hold an operating asset at all versus just holding notes.

The mechanism solder ran into is worth stating precisely, because the size of the dollar amount has nothing to do with the size of the exposure.

The prohibited transaction rules cover transactions between a plan and a disqualified person, and the account owner is a disqualified person to their own IRA. Lending money or extending credit between those parties is one of the listed categories. A short-term advance that is fully repaid can still fall inside that category depending on the facts, and there is no de minimis carve-out written into the statute for small amounts. Whether any particular payment is treated that way is a legal determination that depends on the specific facts, which is why solder's answer came from counsel and not from a forum.

The consequence is what makes this asymmetric. For an IRA, a prohibited transaction involving the account owner can cause the account to lose IRA status as of the first day of the tax year in which it occurred, with the full fair market value treated as distributed. A 602 dollar payment and a 400,000 dollar account produce the same category of problem. Confirm the current rules and any correction paths with a tax attorney, because the details and any available programs change.

On keystone's reserve question, the way to size it is to list every expense the asset can generate that has a hard deadline attached. Property taxes and insurance premiums have dates. A vacancy does not. Fund the dated ones fully inside the entity and treat everything else as a timing problem you can solve slowly.

The broader deployment point: an operating property inside an IRA generates dated obligations. Notes and passive participations generate far fewer. That difference belongs in the yield comparison before you buy, not after.
